A 4-year-old child playing with matches started a fire that destroyed a mobile home and car on the south side Thursday, authorities said.

No one was hurt in the blaze.

The fire was started by the child in a car parked in the carport, and the blaze spread to the mobile home, said Capt. Barrett Baker, a Tucson Fire Department spokesman.

Firefighters were dispatched at 7:36 p.m. to the fire in the 5200 block of South Campbell Avenue, and found the car engulfed in flames and about 25 percent of the mobile home on fire, Baker said.

Crews prevented the fire from spreading to three other mobile homes, and 22 firefighters brought the fire under control in about 30 minutes, Baker said.

The Southern Arizona Chapter of the American Red Cross assisted the family.

City building-safety inspectors condemned the structure, Baker said.

Damage was estimated at $60,000.
